[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of an embodiment of a rivet production quality inspection tooling, including:

[0036] Please see Figures 1-6 This utility model provides a technical solution:

[0037] A quality inspection fixture for rivet production includes a base plate 1 and a top plate 2. A motor 4 is bolted to the side wall of the top plate 2. A groove 5 is formed on the top of the base plate 1. A lead screw 6 is inserted into the output shaft of the motor 4. A retaining ring 7 is sleeved on the outer circumference of the lead screw 6. A fixing plate 8 is bolted to the outer circumference of the retaining ring 7. A retaining strip 9 is connected to the inner wall of the fixing plate 8 via a damping bearing. A retaining groove 11 is formed on the inner wall of the retaining strip 9. A retaining rod 14 is connected to the inner wall of the retaining groove 11 via a damping bearing. A retaining plate 10 is bolted to the top of the groove 5. A sleeve rod 12 is bolted to the top of the retaining plate 10. The outer circumference of the sleeve rod 12... The mounting plate 13 is bolted to the mounting plate 13. One end of the clamping rod 14 is connected to the mounting plate 13 via a damping bearing. One side of the clamping rod 14 is bolted to a clamping plate 17, which is made of silicone. The drive motor 4 causes the lead screw 6 to move the retaining ring 7, thereby allowing the clamping strip 9 connected to the inner wall of the fixing plate 8 via the damping bearing to change its angle. This causes the clamping rod 14 connected to the inner wall of the slot 11 via the damping bearing to change its angle, allowing the movable rod 16 to move within the inner wall of the sleeve rod 12. Consequently, the clamping plate 17 changes its bending inner diameter, facilitating the fixing of the top of the rivet, thus significantly increasing the applicability of the device.

[0038] It is worth noting that, in order to improve the overall working efficiency of the device, specifically, the top of the base plate 1 is provided with square grooves 29. There are multiple square grooves 29 and they are symmetrically distributed. The inner wall of the square grooves 29 is connected to the motor 25 by bolts. The output shaft of the motor 25 is inserted into the telescopic rod 26. The top of the telescopic rod 26 is connected to the protrusion 27 by bolts. The inside of the protrusion 27 is connected to the concave block 28 by a damping bearing. The top of the concave block 28 is connected to the top plate 2 by bolts. By driving the motor 25, the telescopic rod 26 can drive the protrusion 27 to rise and fall. Under the action of the damping bearing, the concave block 28 can drive the top plate 2 to change angles. This facilitates the purpose of multiple angles for the quality inspection rivets and also helps to improve the overall working efficiency of the device.

[0039] The output shaft of motor 25 is coaxially connected to the lead screw via a coupling (rigid / flexible). The rotation of motor 25 drives the lead screw to rotate, which in turn causes the lead screw nut to drive the telescopic rod 26 to move linearly. This is existing technology, and in this article, motor 25 and telescopic rod 26 are used as references only.

[0040] Next, in order to facilitate the clamping plate 17 in fixing the bottom of various quality inspection rivets, specifically, a circular groove 24 is provided on the inner wall of the groove 5. A damper 20 is connected to the inner wall of the circular groove 24 by bolts. A spring 21 is sleeved on the outer circumference of the damper 20. A push plate 22 is welded to one end of the spring 21. A rubber pad 23 is glued to one side of the push plate 22. The spring 21 and the damper 20 drive the push plate 22 to exert elastic force on the inner wall of the circular groove 24, thus facilitating the clamping plate 17 in fixing the bottom of various quality inspection rivets.

[0041] Meanwhile, to reduce the possibility of the movable rod 16 flying out, specifically, the sleeve rod 12 has a slot 15 inside, and a groove 19 is formed on the inner wall of the slot 15. A slider 18 is slidably connected to the inner wall of the groove 19. One end of the slider 18 is connected to the movable rod 16 by bolts. The outer circumference of the movable rod 16 matches the inner circumference of the slot 15. One end of the movable rod 16 is connected to the clamping plate 17 by bolts. The slider 18 is slidably connected to the groove 19. The structural design of the movable rod 16 slidably connecting to the slot 15 makes it easier for the movable rod 16 to drive the clamping plate 17 in the horizontal direction. While cooperating with the locking strip 9 and the locking rod 14 to change the angle of extension and retraction, the possibility of the movable rod 16 flying out is reduced.

[0042] Furthermore, in order to better fix the overall device, specifically, the bottom of the base plate 1 is connected to the support legs 3 by bolts. There are multiple support legs 3, which are distributed linearly and equidistantly. The structural design of the support legs 3 facilitates better overall fixation of the device.

[0043] It is worth noting that, in order to improve the stability during the clamping process, there are multiple motors 4, mounting plates 13 and fixing plates 8. The motors 4, mounting plates 13 and fixing plates 8 are all symmetrically distributed. The symmetrical distribution of motors 4, mounting plates 13 and fixing plates 8 facilitates the clamping of rivets from opposite directions, which helps to improve the stability during the clamping process.

[0044] Finally, in order to fix the bottom of the rivet from multiple directions, there are multiple push plates 22, which are arranged in a ring shape. The ring-shaped push plate 22 structure design facilitates better fixation of the bottom of the rivet from multiple directions, thereby facilitating the fixing of the rivet with the clamping plate 17.

[0045] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0046] The device or equipment models mentioned in this article may be as follows:

[0047] Motor 1: Y802-4;

[0048] Motor 2: YMD602.

[0049] Combination Figures 1-6 The specific usage process of the rivet production quality inspection tooling of this embodiment is as follows:

[0050] 1: When using this type of rivet production quality inspection fixture, the operator moves the base plate 1 to a suitable position using the support leg 3, places the top of the rivet on the top of the round groove 24, and the damper 20 and spring 21 work together to make the push plate 22 drive the rubber pad 23 to fix the bottom of the rivet. Then, the drive motor 4 causes the lead screw 6 to drive the retaining ring 7 to move horizontally inside the groove 5, so that the retaining strip 9 connected to the inner wall of the fixing plate 8 through the damping bearing changes its angle, thereby causing the retaining rod 14 connected to the inner wall of the retaining groove 11 through the damping bearing to change its angle. Subsequently, the movable rod 16 moves inside the sleeve rod 12 connected to the retaining plate 10 by bolts on one side. At the same time, the clamping plate 17 changes its bending inner diameter, thereby clamping the top of the rivet. Since the spring 21 and damper 20 can both extend and retract horizontally, and the movable rod 16 can also move and retract through the slider 18 on the inner wall of the groove 19, the frequency of the drive motor 4 can be adjusted to facilitate the clamping of rivets of various sizes.

[0051] 2: When the device needs to inspect rivets from multiple angles, the staff can use the motor 25 connected to the inner wall of the drive square groove 29 by bolts to facilitate the telescopic rod 26 to drive the protrusion 27 to rise and fall, so that the concave block 28 can drive the top plate 2 to change angle under the action of the damping bearing, thereby facilitating the purpose of inspecting rivets from multiple angles.

[0052] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
